Data Sheet Rev. 1.00 / October 2013 ZSPM1025C / ZSPM1025D True Digital PWM Controller (Single-Phase, Single-Rail) Smart Power Management ICs Power and Precision ZSPM1025C / ZSPM1025D True Digital PWM Controller (Single-Phase, Single-Rail) Brief Description Benefits The ZSPM1025C and ZSPM1025D are true-digital Fast time-to-market using off-the-shelf, optimally single-phase PWM controllers optimally configured configured controller and power block for use with the Murata Power Solutions 25A Power Fast configuration and design flexibility Block OKLP-X/25 in smart digital power solutions. Simplified design and integration The ZSPM1025C and ZSPM1025D integrate a FPGA designer-friendly solution digital control loop, optimized for maximum flexibility Highest power density with smallest footprint and stability as well as load step and steady-state Pin-to-pin compatible with the ZSPM1025A PWM performance. In addition, a rich set of protection controller enabling point-of-load platform designs functions is provided. with or without digital communication To simplify the system design, a set of optimized Higher energy efficiency across all output loading configuration options have been pre-programmed in conditions the devices. These configurations can be selected by setting the values of two external resistors. Available Support Reference solutions are available complete with layout recommendations, example circuit board Evaluation Kit layouts, complete bill of materials and more.
